Product Description

<sup>Introducing the AOC-6840 Series of Intelligent Three-way Control Valves, a masterpiece of engineering designed with a double plug and a robust upper and lower guide structure. These valves come in two primary configurations based on the pathway of fluid flow: the three-way diffluence valve, which features one inlet port and two outlet ports, and the three-way confluence valve, which boasts two inlet ports and one outlet port. These configurations allow for unparalleled versatility in achieving fluid mixing, heating, cooling, and unequaled distribution to precisely align with operational demands. Perfectly tailored for the petroleum industry, this series excels in regulating fluid temperature on heat exchangers, ensuring optimal performance and efficiency.

The AOC-6840 series is equipped with a multi-spring pneumatic reinforced actuator that simplifies on-site conversions between normally closed and normally open states with ease. The innovative design provides exceptional protection for the spring from corrosive elements, significantly extending the actuator's service life while enhancing operational convenience. Further, the actuator seamlessly integrates with the intelligent valve positioner through a pipeless connection, bolstering its anti-corrosive performance and ensuring precise and stable adjustments. This harmonious integration ensures exact control over working conditions, meeting even the most demanding requirements with unmatched precision.</sup>
